Mexico Earthquake Saturday: 6.1 Magnitude Aftershock Rocks Capital

Another earthquake measuring 6.1 degrees on the Richter scale has shaken Mexico City early on Saturday morning - it is the strongest aftershock since the 6.8 degreee quake that shook much of the country on Thursday. The epicentre of the shake was in Tecpan, in the state of Guerrero. The earthquake and its aftershocks have been felt in the states of Guerrero, Morelos, Michoacán, Jalisco, Oaxaca, Veracruz, Estado de México, Distrito Federal (Mexico City) and other areas.

Mexico's earthquake on Thursday saw many office workers running out of their building fearing the worst. "There are no immediate reports of any damage in the states where the earthquake was felt," said Interior Minister Miguel Osorio Chong in a post on Twitter. Mexico's National Seismology Service explained that when an earthquake of considerable magnitude strkies, the rocks in the zone surrounding the epicentre are loosened, often provoking further shakes.

Mexico City has thusfar escaped damages. The city, built on unstable sediment, is highl suceptible to damages from earthquakes. On the 19th of September 1985, an earthquake with a magnitude of 8.1 on the Richter scale destroyed large parts of the city and resulted in 3,700 dead, according to official records, however, human rights groups have since put the number closer to 20,000. The city has since been preparing itself for the worst with considerable structural changes.
